Why does international calling use so much data?

Each minute of HD voice call uses about 1MB of data. Use Wi-Fi when available to avoid mobile data charges.

Related QNAs

My payment failed during checkout.

Ensure your card details are correct and there’s enough balance. If your bank blocks international payments, enable it temporarily and retry.

The app crashes when I try to place a call.

Please update to the latest version and clear the app cache. Older builds may not be compatible with new routing updates.

Can I use the same number on multiple devices?

Yes — you can log in with the same credentials on several devices. Just note that active calls work on one device at a time.

Error 30009: Missing message parameters.
